Barnacles

 

Barnacle barnacle barnacle
Bob you are a crusty creature
calcareous plated
     Cirripedea
       no heart
           yet
a door with sensors 

Barnacles barnacles barnacles
Purveyors of super strong glue
you cement yourselves on rocks
crab claws and whales
wharfs and hulls
you and your tenacious crew 

Barnacles barnacles barnacles
 the tide’s in
    slide         wide your
operculum!
out with your feathery cirri
wave that plankton in
while you stay put
awash in tidal action
